While the upper section provide access to each main filter's direct output, the lower section has 4 voltage controllable parameters to manage two independent functions for further spectral editing: tilt and parametric scan.
The tilt, as the name suggest, tilts the spectrum, adding and subtracting amplitude to the 16 bands, emphasizing lower or high bands, and attenuating high or lower bands: this is managed only with the green potentiometer.
The parametric scan, instead, works with three parameters: peak/notch, band selector and width. Like in a parametric equalizer, where is possible to set peak/notch gain, frequency and slope, the FUMANA uses three parameters to set which is the centre band to perform this manipulation, then if that band should be emphasized or attenuated, and how this action is extended to nearby bands.
In addition to the 16 bandpass outputs, there are other 4 outputs provided: the all bands output, the all envelope followers output, the odd bands and the even bands output. These two have the options to be inverted in phase with two switches, in order to obtain even more combination when summed together, maybe/also with the "all bands output", using, for example the 333 module.
Since a spectral transfer tool may be used as a "vocoder-like-effect", the FUMANA provides an input for an external noise which may be used for unvoiced (fricative/sibilants) sounds as words containing or starting with s, f, z, ch and other fricative sounds.
The USB port of the front panel can be used with any USB powered lamp.
The module is included in each UNO made starting from 2017, but is also available as a standalone module by fixing the 1/4" jacks board on your case.
It is composed of three identical sections, the red, yellow and green, where each of those is capable of scaling any signal, from 0 up to 2 times (+6dB), flip its phase, and apply a DC offset, allowing to shift your audio or CV up or down.
In case no signals are connected to the section input, the offset may act as a CV source too.
The three sections are then summed together into two independent summing stages: the top right jack outputs the sum of all three sections, while the top left outputs the sum of the unconnected sections only (semi-normalled).
The 321 is entirely DC coupled, allowing the process of control voltages as well as audio signals.
In case CV's or audio signals are particularly hot, the two 6dB attenuators, one per each summing section might be helpful to reduce exactly by 50% the incoming signals.
The Channel manages mono signals via the 3.5 mm input mono jack. It has a main stereo VCA with CV in and attenuator (RED), a direct output post main VCA (pre or post fader), two parallel sends with mono VCA with CV in and attenuator for each send and pre/post fader switch (YELLOW and GREEN), and a PAN control with offset CV and offset pot. This, together with the latching buttons for mute, solo in place, and PFL, manages the incoming signal and distributes it to the Group module.
Three boards are included in each UNO case, with 3 flat cables (9 connectors each for the 84HP, 12 each for the 126HP). The boards are mounted inside each metal row without front panel in order to do not waste any precious HP.
The Group gets and sums the L/R post fader signals (WHITE) of all the linked Channels, sums all the signals from the YELLOW and GREEN sends, and manages the sends (mono) and returns (DUAL MONO or STEREO), summing it to the signals from the CHANNELS. It also manages the solo in place activation on all the linked Channels, and provides a L/R output for the outgoing signal, or (via a jumper on the back of the module) a L/R output of the sum of the returns signals.
The Master sums the incoming signals from the Groups, and manages the PFL (stereo) of both Channels and Groups. It also features a stereo in via a 3.5 mm stereo jack with PFL latching button and a stereo out via 3.5 mm stereo jack for headphones, whose signal can be blended between PFL (BLUE) and main out (WHITE).
